I had my rental property painted.

That chuck of change could go a long way towards renovations like a small bathroom remodel, interior painting, or new flooring, etc. if you choose to sell at a higher list price. 

Your tenants and their kids are drinking that water - if you won't drink it neither should they.I'm not trying to be up on a high horse - I didn't know how bad the were until I saw one being repaired... no stop rip all that stuff out.

My tenant’s dog has ripped the linoleum flooring in the kitchen.

In two months you can only clean up, paint and carpet, maybe a few other easy things (there is always something!). 

We updated the unit cosmetically through paint and furnishings, as well as consolidated the kitchen and added more living room space.

My (non lawyer) read of the SC rules paints a much different picture in those jurisdictions than what you discuss in TX - where it sounds like you own effectively nothing but a tax note until the close of the redemption period - you can't take possession and rent the property, real estate taxes during the period are still the responsibility of the original owner, etc.The below is from the County of Charleston SC's website regarding the tax sale and how they work in that particular jurisdiction - certainly not the authoritative source of their state statutes, but for posting on a forum, I'll take it for now. 

NOT a big deal, Scrap and paint the windows or better yet just replace them.

Remodel a kitchen/bath/new paint/maybe some new LVP flooring?
